ADJUSTABLE SUPPORT FOR ELECTRIC FANS.

To all whom it may concern:

Be it known that I, EDGAR "W. BROWN, a citizen of the United States,residing at Dayton, county of Montgomery, and State of Ohio, haveinvented certain new and useful Improvements in Adjustable Supports forElectric Fans, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part of same.

My invention relates more particularly to means for altering andadjusting the position of the body of a fan motor in reference to itssupport, for the purpose of altering the direction in which the air isthrown.

In the drawings, Figure 1 is a side elevation of a fan motor embodyingthe features of my invention. Fig. 2 is a rear elevation of the same.Fig. 3 is a cross-section, taken on the line a b, Fig. 1, looking in thedirecarrow. Fig. 4 is a cross-section taken on the line 0 (Z, Fig. 1,looking in the direction indicated by the arrow. Fig. 5 is a verticalcross-section taken on the line 6 f, Fig. 2. Fig. 6 is a view of awasher-like spring, used for a purpose hereinafter described.

In the several views, in which like characters refer to similar parts, Ais the motor body of the fan motor, to which is cast the lug B, in whichis securely fastened the stud C, which is made hollow to provide apassage for the Wires D, from the base E, to the motor body A. The upperextremity of the base E is divided by an opening, into the sides F andG, between which are fitted the members J and K, which are hollowed outto receive the stud C. Extending outwardly from the member K is anaxle-like projection P, which is fitted in an opening in the side G, andadapted to turn therein. About this projection as an axis, the fan motorbody can be tilted or turned through various angles in a vertical plane.About the stud C as an axis, the fan motor body can be turned throughvarious angles to the right or left, and by combining or using both ofthese movements, the air can be directed to any angle in any plane. Thetongue L, eXtending from member J and fitting a corresponding groove inmember K, aids in maintaining the said member J in its proper position.The lug B is lengthenedout on one side to act as a stop, in order toprevent twisting the wires. This is best shown in Fig. 4. In the side Fof the upper extremity of the base is Specification of Letters Patent.Patented June 13, 1911.

an opening in which is screwed the screw plug H. Between said screw plugH and the member J is placed a washer-like spring I, which is shownseparately in Fig. 6. The screw plug H compresses the spring I andcreates an elastic pressure which compresses the stud G between themembers J and K, which members are also compressed between the saidspring I and the side G of the base. The tension of this compression canbe adjusted by screwing the screw plug H in or out. This tension can beincreased to the point where it would be impossible to turn the motorbody, but for general use this te11- sion would be adjusted to such apoint so that the motor body could be readily turned with the hand andat the same time be firmly maintained in the new position. In Fig. 1,where the dotted outline of the base is shown, it will be noted howreadily this fan motor can be changed to the bracket type of fan, forthe purpose of fastening same to the wall or other vertical surface.

Fans now in use, which are adjustable to different angles are,I believe,without exception held in position with screws or nuts of one kind oranother, and it is necessary to loosen and tighten the same every timeit is required to change the direction of the breeze. In my invention, apressure of the hand is all that is necessary to adjust the motor bodyto a new position and this ad justment is controlled and the position ismaintained by an elastic pressure which is adjustable and actsautomatically.

Having described my invention, I claim:

1. In an electric fan, a motor body, a stud secured thereto, membersfitted to said stud, a support in which said members are held and meansfor clamping both said stud between said members and said members insaid support.

2. In an electric fan, a motor body, a stud secured thereto, membersfitted to said stud, a base or support in which said members are held,means for producing an elastic pressure adapted to compress said studbetween said members and to compress said members in said base orsupport.

3. In an electric fan, secured thereto, members fitted to said stud, anda base or support in which said members are held; means for producing anelastic pressure adapted to compress said stud between said members andalso adapted to compress said members in said base; means a motor body,a stud for adjusting the tension of said elastic pressure.

4. In a device of the character specified, the combination with asupporting member, and a movable body, of clamping members forming apivot upon which said movable body may be turned to various angles in avertical plane, means forming an axis upon which said movable body maybe turned in a complete circle in a plane at right angles to saidvertical plane, and means adapted to exert a yielding pressure upon theclamping members to maintain said movable body at any desired anglerelative to the supporting member and to permit the position of saidmovable body to be changed without changing the tension of the means forsupplying the yielding pressure.

5. In a device of the character specified, the combination with amovable body, and a supporting member therefor, of clamping membersmounted in said supporting mem ber, said clamping members providing apivot upon which said movable body may be moved through a verticalplane, a stud interposed between said clamping members and said movablebody and forming a pivot whereon said movable body may be moved througha plane at right angles to said vertical plane, and means adapted toexert a yielding pressure on said clamping mem-' bers to maintain saidmovable body at any desired angle relative to said supporting member.

6. In a device of the character specified, the combination with amovable body, and a supporting member therefor, of clamping membersmounted in said supporting member, said clamping members providing apivot upon which said movable body may be moved through a verticalplane, a stud projected from said movable body and'engaged by theclamping members, said stud providing a pivot upon which said movablebody may be moved through a plane at right angles to said verticalplane, and means adapted to exert a yielding pressure to maintain saidmovable body at any desired angle relative to said supporting member.

7. The combination with a motor body, and a supporting base the upperextremity of which is provided with an opening inclosed by a series ofabutments, of an apertured stud projected from the motor body and lyingwithin said opening, clamping members arranged between said stud andsaid abutment, and a resilient member adapted to clamp the stud betweenthe clamping members and to apply elastic pressure which is adapted tohold the motor body in a position relative to the supporting basewithout changing the tension of the elastic pressure. 7
